Advanced Oxidation Processes to remove organic micropollutants from (waste)waters

In sustainable water management, the removal of organic micropollutants from (waste)waters is indispensible but extremely difficult. Advanced  Oxidation Processes (AOPs) like ultrasonic irradiation, ozonation and peroxone oxidation, and heterogeneous photocatalysis offer technological breakthrough solutions. However, full mineralization of complex chemicals such as pharmaceutical residues by AOPs is not cost-effective, and therefore partial degradation to more biodegradable or less toxic intermediates is the key. To unravel degradation pathways and to quantify micropollutant residues, attention is given to mass transfer mechanisms, degradation kinetics and process optimization.

Advanced oxidation processes, based on the production of highly oxidative and non-selective hydroxyl radicals, have the potential to upgrade conventional biological wastewater treatment plants that were initially not designed to efficiently remove hazardous organic micropollutants.
